That which separates you from your real Self--the whole and real--is
your ego. You may wonder how you can cut down that ego or may try to
tear it down or forget it, but that's not possible. Instead, you have
to learn to "polish" or train your ego. When the ego becomes aware of
the Reality, it is trained, and then the ego is useful. If the ego
does not remain aware of the Reality, then the ego becomes unhelpful;
it is then harmful or an obstacle.*
